- ATTORNEY-5 Patented Sept. 26, 1933 Application April 7,1932. Serial No. 603,863 is Claims. (01. 188-204) An object of the invention is to provide abrake for automotive and other vehicles which will exert an equal braking effect at the several wheels.

Another object of the invention is to provide a floating means which engages members operating the brakes at theseveral wheels when the floating means is moved by its support.

Still another object of the invention is to provide a floating means which serves as a wedge and engages at its opposite sides levers operatively connected with the brakes.

The invention also comprehends a floating means centrally supported and which has annular guideways engaged by levers operatively connected with the brakes. I l

Additional objects of the invention will appear in the following specification in which the preferred form of the invention is described.

vIn the drawing similar reference characters refer to similar parts in all the views, of which Figure 1 is a perspective diagrammatic view illustrating the means for operatively connecting the brake with the wheels,

. Figure 2 is an enlarged cross sectional view of 25, the subject matter of this application,

. Figure 3 is a sectional view on the line 3-3 of Figure 4, and similar to the view illustrated in Figure 2, but in Figure 3 the floating wedge means has been raised to operative position, Figure 4 is a plan view of the brakingmeans shown in Figures 2 and 3, and v Figure 5 is a sectional view on the line 55 of Figure 4. y l By referring to the drawing it will be seen that shafts 6, '7, 8 and 9 are connected by arms 10 and links 11 with any standard braking means 12. The shafts 6 and 8 are 'connectedby a bearing 13 and the shafts 7 and9 are connected by a bearing 14. An arm 17 is secured to the shaft 6, an 40 arm 18 is secured to the shaft 8, an arm 19 is secured to the shaft 7 and an arm 20 is secured to the shaft 9. As will best be seen by referring to Figures 3 and 5, the arms 17 and 18 have bifurcated ends 21 and each of the shafts 19 and 20 has a tongue 22. which is embraced between the. bi furcated ends 21 of the shafts .17 and 18 respectively. The arms l'l-and 18 have shoulders 1'7 against which the tongues 22 rest when the brakes are not operated andthe arms 19 and 5 20 have shoulders 19 against which the bifurcated ends 21 rest when the brakes are not op.-

erated.

As will best be seen by referring to Figure 4, a

transverse member 23 is provided which has an 55 aperture 24 in which is disposed a stud 25, the

and 20, it will move upwardly relatively to the stud 25 having a ball 26 engagingthe underside of the transverse member 23'at its aperture 24," the stud; 25 also having at its other end a ball 27, an operating lever'28 being provided which has a bifurcated end 29 for embracing the stud m 25 below the ball 2'7. The lever 28 is pivotedat 30 and may be operated byany suitable means, such as the pedal 31. v The transverse member 23 has two apertures 32, the apertures 32 being disposed one at each end of the transverse member 66 23 and in each of these apertures 32 there is dis- I posed a stud 33 havingv a ball 34 engaging the top of the transversememb'er' 23, each 'of the studs 33 being secured by any suitable mea'n s' to a. bracket 35. There ismounted in each (if-them brackets 35 an annular member 36 having; a guideway. Preferably the-annular wedge guideways 36 are 'rotatably .mounted in the brackets 35. As will best be seen by referring'to Figures. 2 and 3, the arms 17 and:1'9 of one pairaredis- .16 posed in theg'uideway in 'oneof' the members 36 and the other pair of arms" 18- and 20 are disposed in the guideway in'the other member 36. f The bifurcated arms 21 of the arms 17 and 18" are disposed above the annular wedgevguidevyays 36, and the tongues 22 of the arms 19' and 20 are embraced between the bifurcated arms 21 of the arms 17 and 18 respectively above the an; nular members-36. f r It will be understood 'from' the above; that, 86' when the lever 28 is operated, itjvvill movefltlie transverse member 23 upwardly; but'that the said transverse member 23 'may rotate relatively to the lever 28 and that it may also tilttransversely relativelyto the ;lever 28. H

It'will, therefore, be seen that a universal joint is provided between thetransverse member' '23 and the lever 28.1 It will also be seen thatT'the brackets 35 may rotate relatively to the 'ftrans verse member 23" and that thesaid brackets 3.5 95.

may also t'iltlaterally or longitudinally of the. vehicle relatively to the'transver se member 23. Therefore, when the lever 28 is operatedto raise the transverse member 23, the pressure' will be equalized 'at each of the arms 17, 18, 19 and 20 for, when the movement of one of the said arms is delayed, the transverse member 23 andithe brackets 35 will adjust themselvesto' distribute the pressure at the other arms to equalize the pressure at the several arms. When 'the resist- Q ance to the movement is greater at the arms 17 a and 19 than at the arms 18 and 20, the "transverse member 23 will be tilted so'that, at the arms 18 end of the transverse member at the armsgl'l' and 19. It will also be seen that, should the resistance at-the arm 17 be greater than at the arm 19, the transverse member 23 may rotate on thestud to move the end of the transverse member 23 at the arms 1'7 and 19 away from the arm 1'? and in. the direction of the arm 19. It will also be understood that where the resistance to the movement is greater at the arms 1'] and18 than at the arms 19 and 20, the transverse me'rnbe'rl23 may move inthe'direc'tion of the arms 19 and 20 to equalize the pressure.

will be equalized in all cases to operate the brakes evenly at the several wheels.
